Volvo 630 with cummins ISX

Recommended Posts

Well trying to pry my cat powered 610 from the owner is becoming a lesson in frustration that I do not need.  I am looking at a 99 VNL630 with the cummins ISX motor.  The truck is used all fall to haul grain and then put away inside.  It has 825,000 miles and I will see what maintenance records there are tomorrow when I look at it.  I have purchased a 610 with less than 400k miles, it was an M11, and two 770 with Volvo engines with around 800 plus miles.  Now the engines in the 770 were strong engines and did not have any problems.  Is the ISX with normally good maintenance a million mile motor or close to it?  It also has an autoshift, which is nice, sometimes.  I kinda like shifting for myself.

I know there are a ton of these engines out there, that is usually a good thing.

Thanks Chuckd

I have a 770 w/ an ISX 500 and Eaton auto shift.  I like it, a lot.  Only issues I've had with the motor were a leaking high pressure fuel pump, and a IFSM plate that was sucking air. (Google IFSM).

Neither were cheap fixes, but nothing's cheap on diesels, especially labor.

M11 is pretty low drama plain-jane engine and seems to work well for us , besides trucks lots of M11's  run a lot in industrial applications so thousands of used engines are on the market cheap.

Every decent shop know both the ISX & M11 so your never far from parts and service all it takes is $$$$

 

Drive on..........(whats cheep in trucks....)

As long as it is a red head, you will be able to find someone to work on it anywhere and the parts will be easy to find.

I totally agree. And rebuilds are "relatively" cheap. Last I checked on an ISM it was in the 13K area for an in-frame.  Everyone seems to know how to work on these. And the earlier ones were relatively bulletproof with a B50 of  1M. Even the ISX15 , which has a bunch of pollution stuff on it, maintains a B50 or over 1M.
